Non-metal is a non-metallic properties different from the metal, there is a negative electric charge is doyoloha C, also known as carbon Graphite electrically conductive properties, good heat resistance, high strength.
Non-metal is a metal with properties of non-ferrous metal is charged negatively by the carbon C is also known as Graphite has a good thermal conductivity is very strong.
Non-metal non-ferrous metal is different from the feature is a negative charge by the metal used is carbon C or also known as Graphite. Has a better heat conductivity is very strong.
